What causes this issue?

The specifications you made to add a table are invalid. The table and
field information has to meet certain requirements:
The table must not be a SAP standard table. Also it has to be active in
the dictionary.
The table must be conversion relevant. It is not possible to assign a
priority handling to a table that will not be converted.
The table has to have a key conflict with priority handling. During the
conversion a key conflict has to be possible. This happens when a key
field of the table is converted and two sets can end up with the same
key. The standard conversion logic has to determine the data set that
shall be kept. (You specified this for example during the mapping of the
company codes)
The used logic that determines the data set which shall be taken has to
support special priority handling.
The specified field has to be a key field of the specified table.
The specified field has to be conversion relevant for the company code
merge
The leading table has to be part of the Special Priority handling.
The specified Table must not be part of the special Priority handling,
already.
